Guide To Designing Low Power Handhelds

Posted by Hemos on from the learning-all-about-it dept.

randomErr writes "iAppliance had a nifty article about designing handhelds. As the state-of-the-art in low-power CPUs races forward, the CPU becomes one of the most critical components in the design of a handheld. New CPUs such as Intel's XScale, Alchemy Semiconductor's Au1000, and Transmeta's Crusoe provide the ability to scale clock frequency and voltage dynamically. As power consumption varies linearly with clock speed and as the square of core voltage, you'll want to have hardware hooks to be able to adjust both clock speed and voltage as necessary, based on device performance."

    i dunno..do those things put out enough power to handle my liquid nitrogen cooling pump without a hiccup to the CPU? [grin]

    You might have seen it already but this is me powering an Amulet2 off a mouse wheel. They are very robust.

    Oh, it was that kind of mouse wheel! I thought you meant the one between the two mouse buttons.
